ENIAC was built
The ENIAC was programmed with plug board and switches. Its speed was 5000 operations per second. It also took up 1000 square feet. -
Period: to
First Generation
The first computers were enoormous, often taking up entire rooms. These computers could solve only one problem at a time because they needed to be physically rewired with cables. -
Cathode-ray was modified
It was modified by Sir Frederick Williams of Manchester University. It paints dots and dashes of phosphorescent electrical charge on the screen. -
IBM's Selective Sequence Electronic was first used
The speed is the Selectie Sequence Electronic was 50 multiplications per second. The technology used was 20,000 relays, 12,500 vacuum tubes. The leader of this project is Wallace Eckert -
The EDSA is assembled by Maurice Wilkes
It's the first pratical stored-program computer. It used vacuum tubes and its speed was 714 operations per second. -
Britain's Pilot ACE was completed
It was directed by Alan Turings. It used 800 vacuum tubes. It also took up 12 square feet. The leader of this project was J.H, Wilkinson -
Period: to
Second Generation
The second generation of computers, such as the IBM 1401 mainframe were physically smaller, less expensive, more powerful, and more reliable. -
COBOL
A programming language. It was used for programming business applications and many more things. -
IBM's 7000 series
IBM's 7000 series mainframes were the company's first transistorized computers. At the top of the line of computers- all of which emerged significantly faster and more dependable than vaccum tube machines- sat the 7030, the "Stretch". -
LINC
The LINC is a Laboratory Instrumentation Computer that was offered the first real timelaboratory data processing. It was designed by Wesely Clark. -
Minicomputer: PDP-8
It's the first successful minicomputer by digital. It's the size of a fridge. It also used transitors and magnetic core memory. -
real-time reservation system
IBM developed the real-time computerized ticket reservation system for American airways. It's smaller than SAGE. It's called the SABRE ( Semi-automatic business-related environment) -
IBM's system 360
It was a mainframe computer system family. It's consisted of 6 processors and 40 peripheral units. -
BASIC
BASIC is a programming language as a tool for the novice programmer. zit allows for awide range of applications, and it has many versions. -
Period: to
Third Generation
Integrated circuits marked the begining of this generation such as the IBM system 360 mainframe. -
Digital Equipment Incorporation introduced the PDP-8
The PDP-8 was the first commercially succesful minicomputer. It had spped, was small, and it was a reasonable cost so it went into thousands of manufacturing plants, small businesses and scientific laboratories. -
Department of Defense Advanced Research Projects Agency
This worked with the University of Illinois and built a large parallel processing computer called the ILLIAC IV. this computer did not operate until 1972, but it achieved a computation speed of 200 million instructions per second. -
Standard metal oxide semiconductor
Fairchild Camera and Instrument Corporation built this first for data proccessing applications, also, by using the integrated circuits, Medtronics constructed the first internal pacemaker. -
Evans and Sutherland
David Evans and Ivan Sutherland founded a company to develop a special graphics computer known as a frame buffer. This was a special high-speed memory used for capturing video. The two founders trained a generation of computer graphics pioneers. -
Intel
Intel was founded in 1968 abd is short for Integrated Electronics. The magnetic core memory was replaced buy a microchip during this time, too. -
Invention of Mircroprocessor
The microprocessor contains the core processing capabilities of an entire computer on one single chip -
Pascal
Nikalaus Wirth created Pascal, a programming language. Wirth is a Swedish computer scientist. This language was specifically designed to teach concepts of structured programming. -
Period: to
Fourth Generation
The invention of the micro-processor in 1971 ushered in the fourth generation of computers. -
8008
8008 is an 8 bit processor powerful enough to be used as the CPU of a minicomputer. It was released by Intel. -
Altair 8800
It was developed by MITS. it used the 8-bit Intel 8080 microprocessor and was made avaiable in a complete kit. It contains 256 bytes of RAM -
Apple
It was founded by Steve Wozniak and Steve Jobs. They built a microcomputer motherboard that used a 8-bit processor. The motherboard was a single circuit bord and held 4 kb RAM. -
Pretty Good Privacy is introduced
It's an email encryption program. Its inventor was Phil Zimmerman. He created it as a tool for people to protect themselves from intrusive governments. -
Terminator
It featured ground-breaking special effects done by Industrial Light and Magic. It was the most expensive movie of its time due to computer generating special effects. -
Masiac web browser is relaeased
It was the first commercial software that allowed graphical access to content on the Internet. it was designed by Eric Bina and Marc Andreessen. -
Period: to
Fifth Generation
Fifth generation computers habe no precise classification because experts disagree about its definition. -
Video Toaster
It was introduced by New Tek. It was a video editing and production system for the Amiga line of computers and included custom hardware and special software.
